The focus of this outcome study was on art therapy as a support for medical treatment and palliative care. A total of 41 patients were placed in 2 matched groups: 22 patients with Parkinson's disease and 19 patients without Parkinson's disease. Each participant completed the Brief Symptom Inventory (BSI) (Derogatis, 1993) pre- and post-session,…

An extensive body of research claims that labels facilitate categorisation, highlight the commonalities between objects and act as invitations to form categories for young infants before their first birthday. While this may indeed be a reasonable claim, we argue that it is not justified by the experiments described in the research. We report on a…

Four experiments examined children's inferences about the relation between objects' internal parts and their causal properties. In Experiment 1, 4-year-olds recognized that objects with different internal parts had different causal properties, and those causal properties transferred if the internal part moved to another object. In Experiment 2,…

Two styles of test interpretation (TI), delivered and interactive, were manipulated in a 1-session counseling interview. The favorability of the interpretations (i.e., positive only and mixed) was also manipulated. After completing a well-known personality test, 46 participants completed the TI session. Participants' thoughts and perceptions of…

Introduction: This study examined the validity of tensiometry as an objective method of assessing the improvements in the quality of knots and technical performance due to practice on suturing and knot-tying skills. Methods: We evaluated the quality of 1,830 knots produced by undergraduate medical students before training (pre-test), after…

There is little experimental evidence that any non-human species is capable of purposefully attempting to manipulate the psychological states of others deceptively (e.g., manipulating what another sees). We show here that chimpanzees, one of humans' two closest primate relatives, sometimes attempt to actively conceal things from others.…

The authors investigated the mechanical basis of length perception through dynamic touch using specially designed rods in which the various moments of mass distribution (mass, static moment, and rotational inertia) were varied independently. In a series of 4 experiments, exploration style and rod orientation were manipulated such that the relative…

How does an observer decide that a particular object viewed at one time is actually the "same" object as one viewed at a different time? We explored this question using an experimental task in which an observer views two objects as they simultaneously approach an occluder, disappear behind the occluder, and re-emerge from behind the occluder,…

Three experiments were conducted to evaluate response allocation of stereotypy during free-operant and restricted-operant conditions. Five children with autism or related developmental disabilities participated in at least one and up to three of the experiments. In Experiment 1, the stereotypic response that emerged as most probable during a…

Having young readers manipulate objects to correspond to the characters and actions in a text greatly enhances comprehension as measured by both recall and inference tests. As a step toward classroom implementation, we applied this manipulation strategy in small (three-child) reading groups. For successive critical sentences, one child would read…

Acquisition of verbal behavior is a major goal of interventions for children with developmental disabilities. We evaluated the effectiveness of manipulation of an establishing operation for functional discriminated mands. Four individuals with developmental disabilities participated in a training procedure designed to teach two separate mands for…

Language and social interactions were examined between a father and mother and their twin children, one with Down syndrome and one developing typically. Systematic observations were made of videotaped segments and coded in real time using a computerized behavior coding program. Codes for the parents' interactions consisted of total vocalizations,…

Parker and Gibson's developmental model of evolution of language and intelligence in early hominids is described and discussed; data from a comparative study of object manipulation in two apes and a human infant are reported; and, human ontogenic developmental retardation in locomotion is discussed in terms of its implications for the differential…

Because sensorimotor and environmental factors have a profound effect on children's learning, every teacher should know how to weave strategies from occupational therapy (OT) into their everyday instruction. This is the guidebook K-3 teachers need to "think like an OT"--and form effective partnerships with OTs in their schools--so all students can…

Previous research has emphasized the role of within-match similarity in children's comparisons. The current study investigated another potentially important contributing factor, namely the distinctiveness of the matching items relative to other items in the scene. Using a well-known relational mapping task, we found that 3- and 4-year-olds made…
